GLEON 2024 Virtual Meeting

All Hands’ Meeting, 8-12 April 2024

Held in GLEON’s GatherTown online meeting space.

With the success of in-person and virtual meetings in 2021-2023, the GLEON Steering Committee recognized the value of both meeting formats to facilitate the inclusiveness of online meetings and the kinds of interactions at in-person meetings that are key to the network’s collaborative approach to lake science. They made a commitment to continue organizing All Hands’ Meetings, alternating between virtual and in-person meetings every nine months or so. 

The GLEON 2024 Virtual All Hands’ Meeting, 8-12 April 2024 will be held in GLEON’s GatherTown online meeting space following a similar program and weekly schedule for online meeting activities as before (see below for a Program Overview).

For the first time, the GLEON virtual meeting will have a ‘local’ host from an underrepresented region. For GLEON 2024, the Tanzania Fisheries Research Institute (TAFIRI) will serve as local host to help highlight regional research on Lake Tanganyika, the African Great Lakes, and other regional lake research topics.

The hashtag #GLEON2024 will be used for social media.

Please note: The GLEON website is currently under maintenance. Please bookmark this page for up-to-date meeting information.

The GLEON Student Association (GSA) workshop subcommittee is organizing a pre-recorded workshops for asynchronous viewing. The online videos will be uploaded and available a week before the GLEON 2024 Virtual Meeting. 

  • Hands-on R for Data Exploration and Visualization by Dr. Masumbuko Semba - In today's data-driven world, understanding how to work with information effectively is crucial. This course opens the door to the exciting world of data analysis using R, a powerful and versatile language tailored for statistical computing and graphics. You'll embark on a journey to explore various data types, structures, and manipulation techniques, equipping you to transform raw data into meaningful insights and compelling visualizations. Learn more about the workshop.
  • Science Communication by Rebecca North - This two part workshop will cover science communication and include scientific writing and publishing and tips on how to give an effective conference presentation and prepare a poster.
  • Understanding the real risks of cyanobacterial toxins for humans by Bas Ibelings - In this workshop, Dr. Ibelings will do account of the nearly 10 year-long process and outcomes of the revision of the WHO handbook Toxic Cyanobacteria in Water, which contains the new Guideline values (GV) for a wide range of cyanobacterial toxins. What is the scientific basis for these GV? How do GV differ between hepatotoxic and neurotoxins? What are the uncertainties in the derivation of GV? How does this play a role in their day-to-day application to safeguard the public against risky exposure to cyanotoxins? How do risks between exposure in drinking water, freshwater seafood and recreation compare? Was Toledo – for instance – right in closing the tap water for 10,000s when microcystin was detected in drinking water, connected to blooms of toxic cyanobacteria in Lake Erie, or was continued use of the tap water safe?

There is no fee for the workshops, but those interested in participating should complete a registration form. A workshop Q&A session is tentatively scheduled during the virtual meeting live sessions. If you have any questions about the workshop, please contact the GSA.

    Plenary Speakers and Panel Discussions

    • Day 1: Challenges and Solutions for Lake Tanganyika - Dr. Prisca Mziray (speaker), Dr. Happiness Anold, Mr. Huruma Mgana and Mr. Peter Limbu (panelists).
      • Dr. Prisca Mziray will talk about challenges and solutions for Lake Tanganyika as an introduction to a panel discussion on the topic. 
    • Day 2: Challenges and Opportunities for African Women in Sciences - Angela Nankabirwa, NaFFIRI/ACARE (speaker).
      • Angela Nankabirwa is an aquatic ecologist with expertise in freshwater ecology. Working with a wide range of collaborators, Nankabirwa develops research that balances human interests with protecting biodiversity. Her work uses detailed field studies on the African Great Lakes to gain general insights and identify patterns in the face of increasing global environmental changes. Her goal is to achieve sustainable use of freshwater resources that maintain the integrity of river and lake ecosystems. Nankabirwa also spearheads the African Women in Science program at the African Center for Aquatic Research and Education Organisation. Through this initiative, she fosters inclusivity and empowers women to actively contribute to advancing research and development in the African Great Lakes region and beyond.

    Virtual Meeting Technologies

    GLEON will be using a variety of technologies during the G2024 Virtual Meeting, including GatherTown (for the main meeting platform), Slack (for interactive dialogue), and Zoom (for plenary sessions and regional meetings accessed via GatherTown or Zoom directly).

    The GSA communications subcommittee has set-up a Technical Support (#technical-support) channel in the GLEON Slack workspace to provide information and help answer questions about virtual meeting technologies. They have also prepared "how to" video about using Slack. 

    Beginner's Guide to GLEON

    The GLEON Student Association developed a Beginner's Guide to GLEON to help orient those who are new to the network or attending their first meeting.
